Key Takeaways
Weight is one factor in how much CBD suits a dog, and it is far from the only one. The safe route is to follow the product label, begin at the low end and let your vet guide any change.
We will not give you a figure, because the right amount depends on the product, the dog and its health as well as its weight. Follow the label on a pet product, start low and ask your vet to confirm.
Why Is Weight Only Part of the Answer?
Because two dogs of the same weight can differ in age, health, sensitivity and the medicines they take.
Weight charts are popular because they look precise. A small dog generally needs less than a large one, and that much is common sense. Beyond that, a chart cannot know whether your dog is elderly, unwell or already on medication.
Strength also varies from one product to another. The same number of drops from two different bottles can deliver very different amounts, which makes a general chart misleading.
What Should You Use Instead of an Online Chart?
Use the directions on the specific product, and have your vet check them against your dog.
A product made for pets states its strength and gives usage directions written for that formula. Those directions are a better starting point than anything generic, since they account for how concentrated the product is.
Our guide to using a CBD tincture explains how droppers and strengths work, which helps when reading a pet label too.

Which Factors Should You Raise with Your Vet?
Size, age, health, medication and the reason you are considering CBD in the first place.
The table below shows what each factor changes. It is a guide to the conversation and does not replace it.
| Factor | Why it matters | Who decides |
|---|---|---|
| Body weight | Smaller dogs generally need less | Label, confirmed by your vet |
| Age | Older dogs can be more sensitive | Your vet |
| Health conditions | Liver and kidney health affect processing | Your vet |
| Current medication | Interactions are possible | Your vet |
| Product strength | Bottles differ widely | The product label |
| Your goal | Shapes what to watch for | You and your vet together |
How Do You Introduce CBD to a Dog Carefully?
Begin with the smallest serving the label describes, keep it consistent and watch your dog closely.
Give it at the same time each day and change nothing else in the routine, so you can tell what is having an effect. Keep brief notes on appetite, energy and behavior.
Resist the urge to increase quickly. If your vet agrees a change is worth trying, make it gradually and one step at a time.
What Signs Mean You Should Stop and Call the Vet?
Unusual sleepiness, wobbliness, vomiting, loss of appetite or any behavior that worries you.
Stop giving the product and call your vet if you notice any of these. Take the bottle with you so they can see exactly what your dog has had.
Never give a dog a product made for people. The pet tincture in the pet care range at Pure Standard Extracts is third-party lab-tested and made for animals, with directions on the label.
